Comment form not display properly?

I want to display comment form in my blog page comment_form() work properly but its display like that:

Comment

name

email

website

But this form should be display like that

Name

email

website

comment

I was tried most of demo and snippets but they are not worked. So anyone have an idea about that.

Here is my
comments.php

    <?php
/**
 * @package WordPress
 * @subpackage XXXXX
 * @since Claster 1.0
 * 
 * Comments Template
 * Created by CMSMasters
 * 
 */


if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME'])) {
    die(__('Please do not load this page directly. Thanks!', 'cmsmasters'));
}

if (post_password_required()) { 
    echo '<p class="nocomments">' . __('This post is password protected. Enter the password to view comments.', 'cmsmasters') . '</p>';

    return;
}

if (have_comments()) {
    echo '<aside id="comments">' . "\n" . 
        '<h6>';

    comments_number(__('No Comments', 'cmsmasters'), __('Comment', 'cmsmasters') . ' (1)', __('Comments', 'cmsmasters') . ' (%)');

    echo '</h6>' . "\n";

    if (get_previous_comments_link() || get_next_comments_link()) {
        echo '<aside class="project_navi" role="navigation">' . "\n\t" . 
            '<span class="fl">' . "\n\t\t";

        previous_comments_link('&larr; ' . __('Older Comments', 'cmsmasters'));

        echo "\n\t" . '</span>' . "\n\t" . 
        '<span class="fr">' . "\n\t\t";

        next_comments_link(__('Newer Comments', 'cmsmasters') . ' &rarr;');

        '</aside>' . "\n";
    }

    echo '<ol class="commentlist">' . "\n";

    wp_list_comments(array(

        'callback' => 'mytheme_comment' 
    ));

    echo '</ol>' . "\n";

    if (get_previous_comments_link() || get_next_comments_link()) {
        echo '<aside class="project_navi" role="navigation">' . "\n\t" .

Comment.php

The way I see your comment.php seems messy and more complex than it needs to be, you can post this piece of code to in your comment.php and it should work okay.

<?php 
/**
 * If the current post is protected by a password and
 * the visitor has not yet entered the password we will
 * return early without loading the commend
 */
if (post_password_required()) {
    return;
}

?>

        if (!empty($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME']))

    <div id="comment-area">

        </div>

    <?php endif; // if you delete this the sky will fall on your head ?>

Bear in mind this is without the Website input but that is easy to add 😀

Single.php

Inside your single.php file you can add this line of code to check if there the comments are open and then display the comment_template

<?php 
    if ( comments_open() || get_comments_number() ) {
        comments_template();
    }
?>
